Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing electronic apparatus to receive 5G mobile signals while maintaining a slim and thin appearance poses a challenge, as existing solutions often require additional antenna structures that occupy internal space.
Innovation Solution
Incorporating a metallic frame with gaps between strip-like metallic elements, accompanied by non-conductive elements and a flexible printed circuit board with varying feeding and grounding lines, which functions as an antenna to receive 5G signals without additional antenna structures, allowing for a narrow frame design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional antenna structures are added to receive 5G signals, then 5G signal reception capability is improved, but the internal space of the electronic apparatus is occupied and the frame becomes wider
Solution Approach 1:
The patent merges the antenna function with the metallic frame structure by making the metallic elements themselves serve as antenna elements. The metallic elements form a continuous frame that surrounds the display module, and this frame is configured to receive 5G mobile signals. By integrating the antenna function into the existing frame structure, no additional antenna structures are required, thus avoiding occupation of internal space while maintaining 5G reception capability
Solution Approach 2:
The metallic frame serves multiple functions simultaneously: it provides structural support for the display module, forms the aesthetic boundary of the device, and acts as the antenna for receiving 5G signals. This multi-functionality eliminates the need for separate antenna components, allowing the electronic apparatus to achieve both narrow frame design and 5G signal reception
2Reliability
If additional antenna structures are added to receive 5G signals, then 5G signal reception capability is improved, but the frame width increases
Solution Approach 1:
The antenna function is merged with the metallic frame, allowing the frame to serve dual purposes as both structural boundary and signal reception element. The metallic elements forming the frame are configured to receive 5G signals, eliminating the need for additional antenna structures that would increase frame width
3Length of stationary object
If metallic elements are placed close together to form a narrow frame, then frame width is reduced, but signal reception may be affected
Solution Approach 1:
The patent applies local quality by introducing gaps at specific locations between adjacent metallic elements rather than uniformly spacing them throughout. The gaps are strategically positioned to maintain proper signal reception characteristics while allowing the overall frame to remain narrow. This localized modification ensures that the antenna function is preserved at critical areas while achieving the narrow frame design goal

AI summary
An electronic apparatus includes a display module and a plurality of metallic elements. The metallic elements at least partially surround at least three sides of the display module to form a metallic frame. The metallic frame is configured to receive a fifth generation (5G) mobile signal, in which adjacent two of the metallic elements have a gap therebetween.
